Abstract

The article presents the results of an interlaboratory experiment evaluating the differences in the results obtained by different methods of measuring of specific power of magnetic losses of sheet specimens of oriented electrical steel. Measurements were carried out both with the installation CICL-2 that implements measurement method using field coils and a standardized method with calculation of field magnitude from the current value in the magnetizing winding, and with the measuring systems with different design of yokes implementing a standardized method. The article analyzes the experimental data obtained in order to assess the comparability of measurement results for systems with different design of the closing yoke.
